What Happened
- Union Budget 2026-27 announced the creation of dedicated Rare Earth Corridors in Odisha, Kerala, Andhra Pradesh, and Tamil Nadu — integrated industrial value chains linking mining, processing, research, and manufacturing of rare earth elements (REEs).
- The corridors are designed to cover the entire value chain from extraction to manufacture of high-value products such as rare earth permanent magnets (REPMs), which are essential for electric vehicles, wind turbines, and defence electronics.
- A Rare Earth Permanent Magnet (REPM) Manufacturing Scheme worth Rs 7,280 crore was already approved in November 2025 to complement these corridors.
- The four states were selected because they sit atop India's largest coastal placer deposits of monazite — the primary REE-bearing mineral in India.

Rare Earth Elements: What They Are and Why They Matter
Rare Earth Elements (REEs) are a group of 17 metals: the 15 lanthanides (lanthanum to lutetium in the periodic table), plus scandium and yttrium. Despite the name, most REEs are not geologically rare — they are, however, difficult to extract and process economically because they occur in low concentrations and are chemically similar to each other, making separation complex. REEs are categorised as Light Rare Earth Elements (LREEs: lanthanum, cerium, praseodymium, neodymium) and Heavy Rare Earth Elements (HREEs: dysprosium, erbium, ytterbium, lutetium). The most strategically important are neodymium and dysprosium, which are used in neodymium-iron-boron (NdFeB) permanent magnets — the strongest magnets known, essential for EV motors and wind turbine generators.
- Primary REE minerals in India: monazite (contains thorium, lanthanum, cerium, praseodymium, neodymium), xenotime (yttrium, heavy REEs), bastnäsite.
- India holds the 5th-largest REE reserves globally, with approximately 8.52 million tonnes.
- China controls ~60% of global REE mining and ~85–90% of global REE processing — creating strategic supply chain vulnerability for all nations.
- REEs are listed as Critical Minerals by India's Ministry of Mines (2023 list of 30 critical minerals).
Connection to this news: The Rare Earth Corridors directly address India's critical vulnerability — it possesses large REE deposits but lacks domestic processing and manufacturing capacity, forcing dependence on China for value-added REE products.
India's REE Deposits: Geography and Geology
India's REE deposits are concentrated in two types: (1) Coastal placer heavy mineral sands containing monazite, found in Odisha (Ganjam district), Kerala (Chavara, Manavalakurichi), Tamil Nadu (Thoothukudi, Tirunelveli), and Andhra Pradesh (Srikakulam, Vizianagaram). (2) Primary carbonatite deposits in Rajasthan (Kamthai, Siwana) and Gujarat (Amba Dungar). The coastal placer deposits are the most economically significant for immediate exploitation. IREL (India) Limited — a government-owned company formerly known as Indian Rare Earths Limited — operates processing plants at Ganjam (Odisha) and Aluva (Kerala), currently the backbone of India's REE processing.
- IREL (India) Limited: Central PSU under Department of Atomic Energy; processes monazite and extracts mixed rare earth chloride.
- Monazite also contains thorium — a nuclear fuel — making it a controlled mineral under the Atomic Minerals Concession Rules.
- Basic Customs Duty on monazite: reduced from 2.5% to Nil effective February 2, 2026 (Budget 2026-27).
- Customs duty on capital goods for critical mineral processing: fully exempted (previously 5%–7.5%) in Budget 2026-27.
- Odisha (Ganjam), Kerala (Aluva), Tamil Nadu, and Andhra Pradesh account for the bulk of India's ~12 million tonnes of total heavy mineral sand deposits.
Connection to this news: The four states chosen for Rare Earth Corridors precisely match the geography of India's coastal monazite deposits and IREL's existing processing infrastructure — the corridors build on existing institutional capacity.
Critical Minerals Strategy: India's Geopolitical Imperative
The global scramble for critical minerals has intensified because the green energy transition — EVs, wind power, solar panels, grid batteries — depends on specific minerals that are geographically concentrated. REEs, lithium, cobalt, and graphite are at the top of every major economy's strategic mineral list. India's Critical Minerals Mission (2024) identified 30 critical minerals and announced a phased approach: secure overseas mineral assets through Khanij Bidesh India Limited (KABIL), develop domestic extraction, and build processing capacity. The Rare Earth Corridors represent the domestic processing and manufacturing pillar of this strategy.
- India's Critical Minerals list (2023): 30 minerals including REEs, lithium, cobalt, nickel, graphite, vanadium, selenium, titanium.
- KABIL (Khanij Bidesh India Ltd): JV of NALCO, HCL, and MECL for overseas critical mineral acquisition.
- India has signed critical mineral agreements with Australia, Argentina, and the USA to secure overseas supply.
- Global REE demand is projected to grow 3–7x by 2040 due to EV and wind energy demand.
- NdFeB magnets: ~2 kg of REEs per EV motor; a wind turbine may require 200–300 kg of REEs.
Connection to this news: The Budget's simultaneous announcement of Rare Earth Corridors and customs duty exemptions on capital goods signals a comprehensive policy shift — from merely owning mineral assets to building an end-to-end domestic REE industry.
